Sometimes instead of {POP, GETSTATIC Unit.INSTANCE, ARETURN} sequence
the codegen emits {CHECKCAST Unit, ARETURN} sequence, which breaks tail
call optimization. By replacing CHECKCAST with ARETURN we eliminate
this issue.
#KT-19790: Fixed
Consider call chain `foo.bar.baz()` which has expected type `Int`
Elements `foo` and `bar` doesn't have expected type `Int`,
this is especially important in NI, because we use expected type for
candidate applicability
Before this change, the codegen used to generate beforeInlineMarker
in order to spill variables later. However, since the tailrec call
is replaced with jump, no afterInlineMarker is generated, leading to
inconsistency of these markers. Thus, the spilling fails.
This change disables generating of beforeInlineMarker.
#KT-21521: Fixed
Unlike ordinary lambdas suspend lambdas has create method which invokes
the constructor of the lambda object (continuation).
The inliner could not cope with this.
The previous change fixed the case of suspend lambda without receiver.
This change adds support of suspend lambdas with receiver.
#KT-21605: Fixed
in redundant locals elimination.
Since IgnoringCopySourceInterpreter ignores ALOADs and ASTOREs,
the source instruction of ALOAD K in {ALOAD N, ASTORE K, ALOAD K}
sequence is not ASTORE K. In this case we cannot simply replace K
with N, since there can be multiple {ALOAD N, ASTORE K} sequences
in separate branches. After replacement we get different stack
frames.
This change resolves this.
However, in ReturnUnitMethodTransformer we want to ignore copies
of the same GETSTATIC kotlin/Unit.INSTANCE, since we do not mess
with local variables and just replace ASTORE with ARETURN to help
tail-call optimization.
#KT-23373: Fixed
#KT-21696 Fixed
The problem is coming from the fact that `AnnotationTarget.VALUE_PARAMETER` is mapped to receiver parameter and to value parameter, but annotation with use-site target `receiver` can be used only on type reference of receiver parameter
Fixes #KT-23153 for Kotlin 1.3
The problem was in the type check of expression type against expected type. When feature `AssigningArraysToVarargsInNamedFormInAnnotations` (KT-20171) appeared, expected type could be wrong, which led to failed type check
Use fake continuation instead of ALOAD 0 while inlining
Do not generate state machine for inner lambdas and inner objects,
which capture crossinline suspend lambda.
#KT-19159: Fixed
- Use direct access to property defined into companion object when
it is possible rather than always use an accessor to access the
property.
- Use direct access will speedup runtime performance.
- Avoid to generate useless accessors for companion properties.

Note, that this change potentially has some other effects in corner cases
(like the changed test data that is rather sensible because `bar`
in the example is not effectively projected out and can be called
with nulls)
Probably, we need to consider rewriting all other isSomeType methods
in KotlinBuiltins, but now it seems to be a rather dangerous change
